I respect your point of view when it comes to bitcoin. It wasn't entirely useless if a lot of people are benefiting from it. A lot of people get rich because of bitcoin and I think it is quite rude to say it was useless.
I am on your side. Bitcoin helps a lot of people here. How come it becomes useless? I do not believe in all the propositions given. Based on what I observed, there are lots of us here. And why are all staying here until now? It is just a proof that we are all benefited by bitcoin and other altcoins. Thus, it is useful.
